Up until the latest Direcway firmware upgrade, I was able to use the minimally built-in firewall on the Direcway DW6000 (port blocking) and the Linksys BEFSX41 in series ISP > DW6000 > BEFSX41 > rest of network. The DW firware upgrade has now disabled the firewall portion, leaving me with only one layer. I felt more secure with my multi-layer setup, right or wrongly, now that I am left with theorectically only one layer. Is there justification for installing another component firewall or NAT device into the existing configuration to replace what was lost from the DW? Any hardware recommendations for this, not intending to use ZA or Norton on each workstation?
Thanks.
